如何使用XHR获取PHP文件内容？

Question

How can I get PHP file contents using XHR? I get empty response...

const promise = new Promise(function (success, error) {
    const xhr = new XMLHttpRequest();
    xhr.open('GET', url, true);

    xhr.onreadystatechange = function () {
        if (xhr.readyState !== 4) return;
        if (xhr.status === 200) return success(xhr.responseText);
        return error(new Error(`Failed lo load language data. Server response status: ${xhr.status}.`));
    };

    xhr.send();
}.bind(this));

PHP file contents that I need to get as text:

$_text_block_users = 'Заблокированные ученики';
$_text_id_block_user = 'ID';
$_text_firstname_lastname_block_user = 'Имя, фамилия';
$_text_group_block_user = 'Группа';
$_text_email_block_user = 'Почта';
$_text_contact_person_block_user = 'Контактное лицо';
$_text_telephone_block_user = 'Телефон';
$_text_actions_block_user= 'Действия';

HTTP request to PHP file executes it and returns response (empty in my case). I think it is needed to set some HTTP headers.

The only solution I found is to use simple AJAX. I call some PHP file, get aim PHP file contents with 'file_get_contents()' function and return this contents to the client side (JS). But I am not pleased with this solution... Hope someone know how to make it in most elegant way.
